The first "Salafi" attack attributes shirk to
the expression "I am the Truth." On page three of their
pamphlet they say:

On page 15 of the book The Naqshbandi Way it reads -
"Whoever recites this Ayah even a single time will attain a
high rank and a great position, he will get what the Prophets
and saints could not get, and will arrive at the stage of Aba
Yazid al-Bistami, the Imam of the order who said: "I am
the Truth (al-Haqq)."

We will turn in time, insha Allah, to the explanation of the
statement "he will get what the Prophets and saints could
not get" which the "Salafis" have underlined. For
now it suffices to refute their following objection:

The above statement "I am the Truth" - is a clear
example of Shirk (association) in the aspect of the Names
and Attributes of Allaah, since Al-Haqq in the definite form, is
one of Allaah's unique attributes and is not shared by any
created being or thing unless preceded by the prefix `Abd meaning
"Slave of" or "Servant of".

Answer:

The claim that it is shirk for a creature to say
"I am the Truth" is one of many similar outlandish,
childish rulings of the "Salafis."

Refuting their statement that "Al-Haqq in the definite
form is a unique attribute of Allah not shared by any created
being or thing unless preceded by the prefix `Abd" is
Allah's own statement:

Wa qul ja'a AL-HAQQ wa zahaqa al-batil

Say: HAQQ has come and falsehood has perished (17:81)

The meaning of this verse is enough to show that, contrary to
what they claim, Allah uses the name AL-HAQQ for other than
Himself, namely the Prophet, blessings and peace upon him, and
the Glorious Qur'an.

This is established by hafiz al-Suyuti in al-Riyad al-Aniqa
(p. 143-144):

[Among the names and attributes of the Prophet is:] al-Haqq:
This was mentioned by al-Qadi `Iyad and Ibn Dihya. Allah the
Exalted said: "AL-HAQQ has come to you from your Lord"
(10:108); "Until AL-HAQQ came to them, and a manifest
Messenger" (43:29); "They gave AL-HAQQ the lie when it
came to them" (6:5). One of the two views is: AL-HAQQ here
means Muhammad, sallallahu `alayhi wa sallam, the other
being that it means the Qur'an. Allah also said: "They bear
witness that the Messenger is HAQQ" (3:86), and in the
hadith in Bukhari: "And Muhammad is HAQQ.".

al-Hamdu lillah, the above evidence establishes beyond
the shadow of a doubt that those who claim that al-Haqq
can never be used for other than Allah are lying about Allah and
His Messenger. Therefore Abu Yazid al-Bistami (d. 261) is clear
of their slings and slanders. And how could he not be, when he is
the Imam of the Godwary among the Salaf and is found
praised in the books of the Imams of fiqh, hadith, and tasawwuf,
to the point that Imam Nawawi said in Bustan al-`Arifin:
"If it were permitted, I would compare his sayings to
hadith"?

Below is the defense of Abu Yazid against the slanders of the
"Salafis" from the very one whom the
"Salafis" claim as their leader and teacher in
doctrine, Ibn Taymiyya. In the second volume of the complete
edition of his fatwas entitled Majmu`at al-fatawa al-kubra
Ibn Taymiyya says (p. 396-397):

This state of love is the state of many people from among the
people of love to Allah and the People of Desire of Allah (Ahl
al-irada). When such a person vanishes to himself in the
object of his love -- that is, Allah -- through the intensity of
his love, he will recall Allah, not recalling himself, and
remember Allah, not remembering himself, and visualize Allah (yastashhid),
not visualizing himself, and exist in Allah, not in himself. When
he reaches that stage, he no longer feels his own existence. That
is why he says in this state: ANA AL-HAQQ (I am the
Truth), or subhani (Glory to Me!) and ma fi
al-jubba illa Allah (there is nothing in this cloak
except Allah), because he is drunk with the love of Allah and
this is a pleasure and happiness that he cannot control. From
such states the pen of the Law is lifted.

We would like to ask the anonymous "Salafis" who
claimed that the statement ana al-Haqq constitutes shirk:
Is Ibn Taymiyya claiming that the Shari`a excuses shirk?
Or, rather, have you made up a type of shirk that is not
recognized by your own Imam?
